-
Extract Frames Utilizing the Script:
- Within the terminal window, sort or paste the next Python script. Keep in mind to exchange the supply video file path ("video.mp4") and output picture folder path ("output_frames") along with your particular values.
import bpy import math # Set the supply video path video_path = "video.mp4" # Set the output picture folder path output_path = "output_frames" # Decide the utmost body quantity scene = bpy.context.scene for scene_frame in scene.timeline_markers: max_frame = scene_frame.body # Extract the frames for body in vary(max_frame): scene.frame_set(body) bpy.ops.render.render(write_still=True, animation=False) output_filename = "frame_{:04d}.png".format(body) bpy.knowledge.pictures["Render Result"].save_render(filepath=output_path + "/" + output_filename)- Press Enter to execute the script. Blender will extract every body of the video and save them as PNG pictures within the specified output folder.
-
Rename the Extracted Pictures (Optionally available):
- For a correct sequence of nonetheless pictures, you could wish to rename the default numerical naming format to symbolize the precise body numbers.
